Hmm. No response, other than the trumpeting, which could have been coincidence. So maybe it wasn't a crew member after all.

It seemed that the purpose of the dolphin simulation was to engage in play. Was the purpose of this one to destroy the nearby structures? Perhaps some additional clues would present themselves if he followed the animal's lead.

Experimentally, Zouichi tapped at the bars of a nearby medium-sized cage, bell-shaped: probably for housing birds of some kind, but now empty. Metal, probably some kind of steel. He drew his fist back and struck it hard enough to simply snap the metal supports right off the sculpted rock the cage was mounted on, sending the metal enclosure flying backwards and rolling backwards until it impacted another cage.

...actually, that was strangely satisfying.
